My son has had a rough 3 years with major health issues and is feeling like getting out more now and he is spending money on medical bills so I want to help him with some layering gear. I am going to get him a few first lite merino base layers, I am giving him a down vest and a kuiu super down hooded jacket. He already has rain gear. My question is what would be some good options for a jacket that he could use over the down puffy for glassing when it is pretty cold and could use as an outer layer when he doesn't need the down puffy. I don't mind buying him a couple of jackets for different conditions. Right now he has been using synthetic base layers, fleece, and a Cabelas wooltimate hooded jacket. Thanks for your suggestions.
